In the evaluation of pneumothorax, which imaging modality is used to define bullous disease?

• A. CT chest
• B. Ultrasound
• C. MRI
• D. Nuclear medicine

Answer: (A)

Defining bullous disease in the pneumothorax workup relies on detailed visualization of the lung parenchyma, and CT chest provides the necessary clarity. Its high-resolution, cross-sectional images precisely show the size, number, and location of bullae, distinguish bullae from blebs, and reveal related emphysema or other lung abnormalities. This level of detail informs management decisions and surgical planning, such as bullectomy, and helps assess recurrence risk. While ultrasound can detect the presence of a pneumothorax at the bedside, it does not reliably characterize bullous disease. MRI is less practical here due to limited effectiveness with air-filled spaces, longer scan times, and availability, and nuclear medicine has no role in defining bullae.
